ISAAC DE MISSOURI, ASSIGNOR TO CHARLES SPECIFICATION forming part of Letters Patent No. 716,202,'dated December 16,. 1902. Application filed July 5, 1902. Serial No. 114,519. (No model-l have invented a new and useful Wrench, of

which the following is a specification.

My invention relates to wrenches of the al- Yligatorjtype, and has for its object to design i i .a simple and efficient wrench of this type The simple and novel construction emhaving adjustable jaws.

. .1 ployed by me in carrying out my invention I is fully described and claimed in this specifi- The working parts-of my wrench are ported by a casing consisting of two plates 1- cation, and illustrated in the accompanying drawings, forming a part thereof, in which- Figure 1 is aside view of my wrench. Fig,

2 is a side view of the same with oneside of the casing or handle removed;

" and 2, which also form a handle for operating the wrench. Two toothed jaws 3 aremounted intermediate the plates 1 and'2 and are pivoted on pintles 4:,- theends of "whichare riveted to secure the plates together. -'The jaws 8 have arms 5 formed integral therea with, which arms are engaged by recesses 6,

formed in a head 7.

tracted mouth 6. The arms 5 extend through the mouths 6 and within the circular cavities 6, which permit the free movement thereof. A guide-lug 8, carried by the head 7, engages a guide-slot 9, formed in the plate 2. A stem 10 is integral with the head 11 and is threaded throughout a portion of its length to accommodate an adj usting-nut 12, which carries a cylindrical stop 13, connected to it by a neck 14:. Apertures 15 are formed in the plates 1 and 2 to accommodate the stop 13, which limits the movement of the unut 12 to a rotation about its longitudinal axis.

The plates 1 and 2 are curved at 16 to fit snugly the neck 14. An aperture 12 pierces the nut and serves to accommodate an adjusting-pin.

In using my wrenchth'e angle of, the jaws 3 is varied byturning the nut 12-, which will move the stem 13 longitudinally and swing .the jaws It should be observed that the The recesses 6 each con-"L sists of a circular cavity 6, having a con-f ".jaws are positively operated in both direc tions. 1

I do not wish to be limited as to details of construction, as these may be modified in many particulars without departing from the spirit of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a wrench, the combination of a pair of pivoted toothed jaws located to cooperate to engage a nut, arms carried by said jaws, a head having recesses therein engaging said arms, guides for said head, a threaded stem connected to said head and mounted to move longitudinally, and an adjusting-nut fitted on said stem to adjust said jaws, substantially as described.

2. In a wrench, the combination of a casing constructed to serve as a handle, a pair of toothed jaws pivoted to saidhandle, arms carried by said jaws, a head having recesses therein and bearing a threaded stem, said recesses being located to engage said arms, and said stem being constrained to move longitudinally, and an adjusting-nut fitted on said stem to adjust the angle of said jaws, substantially as described.

3. In a wrench, the combination of two plates forming a handle, of a pair of toothed jaws locatedintermediate said plates and pivoted thereto, arms carried by said jaws, a

head bearinga lug engaging a slot formed in one of said plates, a threaded stem connected to said head and mounted to move longitudinally, and an adjusting-nut fitted on said stem, substantially as described.

4. In a wrench, the combination of two plates forming a handle, a pair of toothed jaws pivoted to said plates, arms carried by said jaws, a head having recesses therein engaging said arms, said recesses comprising a circular cavity having a contracted mouth, a stem connected to said head, and anadljusting-nut fitted on said stem, substantially as described.
